SPLIT-COLLARED SLEEVE FOR ROLLER-BEARINGS.

To all whom Lt may concern:

Be it known that I, CHARLES S.LooK- woop, a citizen of the United States, residing at 289 Market street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Split-Collared Sleeves for Roller- Bearings, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention consists of a modification of the collared sleeve for shaft journals described and claimed in'my application No. 497,087 filed May 19, 1909, to facilitate the application of such collared sleeves to shafts at various points upon their length. This is effected in the present invention by dividing the collared sleeve longitudinally and furnishing the collars with means for clamping the halves of the sleeves together upon the shaft, and similarly dividing the casing so that with its contained set of rolls i't may be applied to the divided sleeve between the collars.

The casing is provided with head-plates or flanges at its opposite ends between which the anti-friction rolls and the cage which guides them are fitted, and the collars upon the sleeve are arranged outside of such headplates to expose the means for fastening the two halves of the sleeve together. The headplates are divided and secured detachably upon the body of the casing so that all parts of the casing and sleeve can be separated from one another for applying them to or Y removing them from the shaft.

- provided with The casing is divided upon an oblique line so as to furnish an oblique joint over which the rolls may pass progressively, and the sleeve is divided upon reversely inclined lines which form an oblique joint favorable to the motion of the rolls.

The halves of the collars upon the sleeve are providedwith lugs for connecting bolts, and the collars are preferably formed with circular guard flanges covering such lugs and bolts.

The invention will be understood by reference to the annexed drawing, in which` Figure, l isa longitudinal section of the bearing applied to a portion ofra shaft and the improvements; Fig. 2 is a plan of the same parts, not in sectin. Fig.

Fig. 7 is an end view, and Fig. 8 an edge view of one of the end collars for the casing. Fig. 9 is an edge view of the cage.

AThe invention is shown applied to a highduty bearing in which short rolls and a short casing can beemployed. '.Thefi'casing is shown with a cylindrical bore a and -an oblique longitudinal division b which separates it into sections c, c, which are provided with lugs d having bolts d inserted through them to lock them together.

Divided head-plates Z are attached to opposite4 ends of the the joint ny of the plates is so arranged that the ends of the plate-sections overlap the joint o of the casing-sections, and positively prevent. any end movement or displacement of the casing-sections. -The head-plates would operate the same if made integral with the easing, as is common.

The ends of the sleeve are extended out-l side of the easing and provided with integral collars and the sleeve and collars divided longitudinally upon the line f, thus separating the sleeves into seetions'e, e, carrying respectively the half-collars g, g. I

The half-collars are providedwith lugs 71,', andI bolts z' are extended -through the same to secure them upon the shaft with the sleeve. The edges o the collars are prdvided with flat circular flanges y' projecting sufficiently to inelose the lugs l1, and the heads of the bolts; which lat-ter are provided with sockets 7c in which a wrench may be inserted between the fianges to turn them.

The collars upon the sleeve lie entirely outside the ends of the easing re the -heads of the bolts are fully accessible to permit the clamping ofthe sleeve-sections upon the shaft or their removal therefrom.

The division of the casing is inclined to the axis of the casing, as shown in Fig. 4, to facilitatethe passage ofthe rolls over the the ends of the line b axial line of the casing indicated by the joint of the casin is formed, at opposite sides of the bore, with rabbets b to hold the .casing by screws m, and

Fig. 4. This inclined l lil m.. i a da halves in place laterally, suoli rabbets extending obliquely across the casingtroni one et its ends to the other, parallel with the joint b., A l

i The division of the sleeve is made oblique for the same reason; but as the sleeve could not be conveniently divided upon an oblique line if such line extended tar around the periphery of the sleeve, l prefer t0 divide the sleeve vupon reversely inclined lines f, extending from the outer side of each collar to the middle of the sleeve between the collars.v V

The joint g of the sleeve is slightly open when the sleeve .is clamped upon the shaft shown at g in Figs. l and 2 so that the screws may bind the sleeve firmly; but the joint of the casing is closed to secure a cylindrical `bore :tor the rolls to traverse. v/

Figs. l, 3 and 9' show the cage having iiat circular rings p at the ends connected by tiebars p between the rolls fr. The rolls are shown tubular, and studs 7" upon the rings loosely ei'igage the ends of the rolls to hold them in the cage.

The rings, like the sleeve and casing, are divided diainetrically for application to the shaft, the connecting ends of the rings being formed with rabbeted or overlapping tongues a. These tongues overlap on the 'outside ot the ends, and the construction thus serves to hold the halves ot the easing from longitudinal displacement within'the casing, while perniitting their tree separation when the casinot is o ened and the an licationto or removal 'trein the sleeve of the rolls carried by the two sections oi "the cage.

From the above description it will be noticed that all the elements of the construction including the cage, the sleeve and the casing are divided diamctrieally and provided where necessary with means for securing their respective sections together so that they may be applied to a shatt at any point in its length.

ilavi'ng thus set forth vthe nature oi. .the invention what isclained herein is:
